Main disconnect switch (isolator), 100A, 4-pole HIS-100/4 142831

Main disconnect switch – reliable power disconnection

This four-pole Eaton HIS-100/4 isolating switch is a robust solution for safely disconnecting electrical installations. Designed for use in both residential and commercial buildings, it provides effective protection against overload and short circuit. Its modular design simplifies installation in distribution boards, and its high durability guarantees long-lasting and trouble-free operation.

Functionality and technical parameters

The HIS-100/4 switch is characterized by a rated current of 100A and a breaking capacity of up to 10kA. The device's width of 4 modules allows for efficient use of space in the distribution cabinet. The IP40 protection class provides basic protection against solid objects, which is important in industrial and construction environments. The use of an "arrow" symbol on the housing facilitates identification of the device's function. Additionally, the possibility of padlock locking increases security, preventing accidental or unauthorized switching on.

This switch ensures the safe operation of most standard installations thanks to a rated current of 100A. It effectively breaks the circuit in the event of a short circuit thanks to a breaking capacity of up to 10kA. The four-pole design allows simultaneous disconnection of all phases and the neutral conductor. Compact mounting in tight spaces is possible thanks to a width of 4 modules. Terminals adapted for conductors with a cross-section of up to 50mm2 provide great flexibility when selecting power cables. Short-circuit strength (Icw) of 2kA ensures resistance to short-term overvoltages. Additional protection against unauthorized access is provided by the possibility of padlock locking.

This switch is not only a safety element, but also a convenient tool for installers. Thanks to its simple installation and clear function identification, it saves time and minimizes the risk of errors during installation. The high continuous current of up to 125A allows it to be used even in more demanding applications.
